If you discuss this on the internet, shills come out of the woodwork immediately to promote glyphosate. I've never seen such astroturfing for any other topic. For example, there are a handful of super user accounts on reddit that pop up at all hours and only discuss this topic and use extremely well researched talking points and citations.
Except astroturfing is coordinated. It's not a conspiracy. The shills you mention are just people who are well-informed on nuanced topic. A topic that that seemingly affects everyone (because food), and therefore everyone chimes in.
Except most people don't know jack about modern food systems and its history. All they know is: big pharma bad, big ag bad, big food bad.
I disagree that these are just people who are well-informed. The frequency and rapid follow up comments by these shills/power users make it nearly impossible for these people to be doing anything else--it's clearly their full-time job. More likely, it's a shared account that some public affairs/relations company shares and they get alerts via keywords and immediately reply. It's very clearly a highly organized machine.
